Notes. Naturalised in the Americas, South Africa, India, New Zealand and southern Australia. Occurs on soils ranging from loams to clays in areas subject to seasonal flooding. Tolerant of high salinity levels and is a key coloniser of saline depressions. Has a short growing period, and matures rapidly after flowering and breaks up. Surface salinity can greatly affect the timing of seedling germination, with germination increasing substantially after salinity levels drop below a certain threshold. Will vary spatially and in abdundance between years depending on rainfall.
